Hi,

I'm extracting pages from a big TIF and creating new files with. But it's taking a long time !!!

For example, for creating a files with the first 50 pages from a TIF of 1500 pages, it's taking around 15 minutes with the command below:
convert in.tif[0-49] out.tif


Thanks

Antoine

How many pixels in each page? What is the computer bottleneck: CPU, memory or disk? Maybe you are running out of memory.

Do you have multiple cores and is OpenMP enabled? Be sure the have lots of tmp space, also.

Its likely ImageMagick is running out of memory so it caching the TIFF images to disk-- which is a performance killer. It works but is slow. Your choices are to accept the slow turn-around, get substantially more memory, or use some other utility.
